  • A fan wrote "Bradley Cooper besties" in the comments and Waterhouse liked it

Suki Waterhouse got candid about her relationship with her ex Bradley Cooper, and it seemed that they weren't that friendly.

Waterhouse dropped her latest single, "Melrose Meltdown," Tuesday. A day following its release, she shared a video on TikTok of her having fun and singing along to her new single, which got her fan's attention, Us Weekly reported.

In the since-deleted video, she used a filter that gave her a lightly colored beard. "Can't believe I let someone who looks like me with this filter break my heart," she wrote in the caption.

One user commented on the video, writing, "Bradley Cooper besties." Waterhouse seemed to confirm it by hitting the thumbs-up button.

Waterhouse and Cooper dated in 2013. They made a few red carpet appearances when their romance made the headlines. They made their Hollywood debut as a couple after nine months of dating by attending the New York premiere of "American Hustle" in December 2013. A month later, Cooper took Waterhouse to the Screen Actors Guild Awards in Los Angeles.

Suki, who is currently dating Robert Pattinson, was tight-lipped about her relationship with the "A Star Is Born" actor.

"I don't talk about my boyfriend because it's boring," she told Elle U.K. "At least, that's what I decided to tell you when you asked. I do think whatever I say will sound weird. But the truth is, if I start talking about him, I probably won't be able to stop. And I don't really want to talk about him, you know?"

The pair split after two years. An unnamed source told E! News that they "remain friends, but they both want different things."

Waterhouse and Pattinson have been dating for over three years already. A source told the outlet that their romance was going strong.

"They are very solid in their relationship," another anonymous insider told E! News in November. "You can tell he's completely in love with her."

As for wedding plans, another insider said they have already discussed getting engaged, but they were in no rush to tie the knot. "Suki is not pressuring him and they are both very committed to each other," the anonymous tipster said.
